How Long Does It Take to Heat a Hot Tub?

Answer

The time it takes to heat a hot tub is based on the wattage the heater is in the hot tub. The heaters come in three sizes, the 1.5kW, 6kW, and 11.5kW. The 1.5k heater heats the hot tub at a rate of 1-2 degrees per hour, the 6k at 10 degrees per hour, and the 11.5kW heater heats the hot tub the fastest at 20 degrees per hour.
